derive-from-key

(Fn [Int, Int, (Ptr CChar), (Ref (Array Byte) a)] (Maybe (Array Byte)))

                    (derive-from-key subkey-len id ctx key)
                

derives a subkey of length subkey-len with the ID id, using the context ctx and the master key key.

keygen

(Fn [] (Array Byte))

                    (keygen)
                

generates a master key for use in key derivation procedures.
